- Muse Code: Meta's first AI coding agent, terminal-based
- Beta for macOS and Linux; parallel sub-agents, action history
- Competes with Claude Code and OpenAI Codex
Meta has unveiled its first AI coding agent, Muse Code. The tool runs in the terminal, is built for large codebases and positions itself directly against the established offerings from Anthropic (Claude Code) and OpenAI (Codex).
Reports by TechCrunch, CNBC and 9to5Mac on 5 August 2026 mention a beta launch for macOS and Linux, parallel sub-agents and a traceable action history. The price is set as a challenge – Meta wants market share in the hotly contested coding segment.
For developer teams, choice grows – and price pressure falls. Competition between Anthropic, OpenAI, Google and now Meta accelerates features and drives down cost.
The pattern is notable: AI agents are moving from the chat window into professionals' tools – terminal, IDE, build pipeline. Anyone building software today should have evaluated at least one coding agent.
